To all whom it wea concern:

Be it known that I, GEORGE I. WIoKs, a citizen of the United States, residing at Cleve.-

Ohio, have invented a certain new and useful Improvement in Adding Attachments for clear, and exact description, reference being had to the accompanying drawings.

he object of this invention is to produce a simple and efficient adding mechanism adaptparticularly a fiat-platen or book type-Writer, so that as numbers are written in column by the type-writer the column-total will becomputed' and registered by the adding mechan- ISIIl.

Other objects subordinate to that stated the preferred embodiment of the invention is developed.

In'the accompanying drawings, Figure 1 is a plan view of a portion of the traveling carriage ofiaFisher book type-writer equipped with my adding mechanism. Fig. 2 is a sectional end elevation of the same. Fig. 3 is a vertical section on the line 3 3 of Fig. 2 designed particularly to show the driving-' gears for the master-wheel. Fig. 4 is a transverse section'al view of the computing device and its supporting means. Fig. 5 is a sectional elevation of the computing device on the -line 5 5 of Fig. 4. Fig. 6 is a detail sectional elevation on the line 6 6 of Fig; 5, showing the rel'ationof a number-wheel and its transfer-dog; and Fig. 7 is a front elevatype-writer equipped with my adding mechanism.

be termed-the actuatorgshaftf? release of the key causes an escapement (not shown) to release the carriage, which then advances the distance of a letter-space, as

usual.

In accordance with my invention the com.- puting device proper is mounted on the frame 1 of the machine, while the operating. mechanism for said device the carriage and is movable therewith, so that as the movement of the carriage advances the printing mechanism to successive denominational positions or orders of the colis 'mounted on 6o umn of numbers on the worksheet the open atlng mechanism will be similarly advanced to correspond ng denominational members of-the computing device.

Secured to the rear of the carriage [rare a in which are 7cpair of supports B and B, mounted one above theother a pail. of parallel shafts O andO,

the "former of which may on the shaft O is a'gear-wheel D, to which is attached a ratchet-wheel d, engaged b pawl 6, carried by an arm amounts to swing from said shaft. The army 2 is con n'ected by a link c with an. oscillatory driving member including an operati-ngarm e Rotatable extended rearwardly from a hollow shaft 6", 8e

]ournaled on a rod e, carried by supports 6 rising from the carriage A. Extended forwardly from the shaft 6 are nine tubular shanks e, in which are secured adjustable arms a pivotally connected to the upper'85 endsof nine vertically-disposed links 6, the

lower ends ofwhich are extended through the top of the carriage-casing and carry rollers e, dlsposed in the paths of the nu- A desi nates the cariiage. of a book typewriter, w ich carriage travels laterally or in the direction of letter-spacing on the machineframe .1 which travels longitudinally of the subjacentfiat platen 2 to line-space the writing. The; carria e A su ports the printing mechanism,.whieh includlis the keys a, their ports l e ml thei'draw-wires a, connected the downwardlyswinging type-bars a. 'The depression of a key-of-the type-writer causes a character as, for instance,- a digit-to be printed on the meral-key levers a in rear of the fulcrums 0, thereof. The links e are guided by links a,

which swing from suitable supports a,

mounted on the late a secured to the to en a numerahkey is deof the carriage. Wh 'ressed, the corresponding'link e by the keylever, and through the inter mediate connections the pawl c. is drawn down to rotate the ratchet-wheel d and the connected gear-wheel D a distance determined by the distance-between the roller e zoo carried by said link, and the fulcrum a of the key-lever. The distance between the fulcrums of the key-levers and the lower ends of. the links e? vary in accordance with the 18 elevated various values of the digits represented by the numeral-keys. Thus the depression ol the 1 key Will cause the rstohehwheel (Z to be advanced a single increment 01 unit of movement as, for instance, the (listsnee of one toothilo tllQ L'lGQlQrSSlOZLQl the 9 key will cause an thee of nine increments 01 teeth, the motion ti'snsii'iitted from the interi'nediste uumemhlteys being similarly proportionate to their respective values.

he Wheel D, which is fixed to tile ratchet d, as stated, is geared to a pinion d, TO tateble on the upper shaft C and fixed. to s gosh Wheel (1 which meshes with a pinion if, keyed or otherwise secured to the lower shaft C, Fig. 3. 'l hiough the medium of this searing s driving connection establishex between the ratchet d and s master actuator, Wheel, 01" pinion c, fixed on the ex-- tended right-hand end of the actuator-shaft C1. The mssteiwheel or pinion a has ten peripheral teeth, and the ratio of the de scribed gearing is such that for each unit of advance of the wheel (2 the pinion c is turned the distance of one of teeth.

The ooniputin (levies PIOPBI is inelosed in s casingl supported by s hi'soket F, located at the rest of the type-Writer and ed justsloly secured to the main frame 1 thereof. The bracket 1 preferably rests upon s plate F extending between the Ctllii? tides G and Sr, lINl is seoui'ed by s bolt l. pissed through the bracket and plate and screwed into a clamp member F bearing against t e under sides of the plate F the ribbon. feed. luck g, fixed to the guide G.

The casing F consists of end pistes f end f emi an intermediate "Well is formed to produce two tubular ehsmhei's and f the .tlenominstiossl Lemhers or numher-Wheels H, located in the letter, being ohsorvahle throu h it sight-op nine f the number 01 denominational I. wheels is immsterisi,
